Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention takes out an arbitrary disc from a plurality of discs stored in a magazine and transfers the disc to a reproducing unit.
The present invention relates to a disc player with a disc changer that stores discs in a magazine after performance, and particularly to a disc pushing mechanism when the discs are stored in the magazine.

[Prior Art] FIG. 6 and FIG. 7 show a disc pushing mechanism of a disc player with a disc changer, which is shown in Japanese Utility Model Laid-Open No. 60-194745.

The disc is driven by the drive roller of the disc changer.
Most are sent to the magazine.

Next, the portion remaining outside the magazine is pushed in by a storage rod provided upright on a storage lever (not shown).

[Problems to be Solved by the Invention] In the above-mentioned conventional disc pushing mechanism, since the storage rod moves in a plane, the storage rod has to be moved from a position outside the movement path of the disc to a position where the disc is pushed in. growing.

Therefore, there is a drawback that not only the mechanism becomes large, but also the time required for storing the disk becomes long.

The present invention has been made to solve the above problems, and an object thereof is to provide a disc pushing mechanism of a disc changer having a compact mechanism and a short operating time.

[Means for Solving the Problems] According to the present invention, a disc pushing mechanism of a disc changer rotates in the vicinity of the magazine of a disc changer chassis for transferring discs between a magazine storing a plurality of discs and a reproducing unit. The body is movably supported up and down, and the rotary body is provided with a pressure contactor and a cam follower.The end face cam is fixed at a position corresponding to the cam follower, and the rotary body presses the cam follower to the end face cam by a spring. By biasing and rotationally driving the rotating body, the pressure contact is rotated to move from a position outside the disk moving path into the disk moving path and push the disk into the magazine.

[Operation] The presser contacts rotate with the rotation of the rotating body, and the cam follower keeps contact with the end face cam to move up and down together with the rotating body.

In this way, the pressure contact can be retracted from the movement path of the disk by moving up and down, so that the stroke can be shortened, the mechanism can be downsized, and the operation time can be shortened.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

 FIG. 3 is a side view showing the overall configuration of the embodiment.

As shown in the figure, the magazine holder 22 provided in the base 20 is mounted with the magazine 21 accommodating a plurality of disks 24.

Disc changer 23 located on the left side of magazine 21
Removes the disc 24 from the magazine 21 and transfers it to the playback unit that plays back the recorded information.
Send 24 to magazine 21.

Although not shown, the reproducing unit is arranged below the disc changer 23.

A part of the disk 24 is extruded by an extruding mechanism provided in the magazine 21, and is drawn in the X direction by a drive roller provided in the disk changer 23.

The disc changer 23 in which the disc 24 is retracted moves in the Z direction shown in the figure to transfer the disc 24 to the reproducing section.

After playing the disc, the disc changer reverses the above operation to feed the disc into the magazine 21 with a part of the disc left at a predetermined position, and the disc pushing mechanism 19 pushes the disc completely into the magazine 21.

Referring to FIGS. 1 and 2, the disc pushing mechanism 19
The structure of will be described.

The shaft 2 is erected on the disc changer chassis 1,
A boss 3 is rotatably fitted to the shaft 2 and its axial position is restricted by a retaining ring 6.

A gear 4 is integrally formed on the lower portion of the boss 3, and pins 5, 5 are press-fitted on the upper portion.

An end surface cam 7 having cam surfaces 8a and 8b is provided around the gear 4.
Are fastened to the disc changer chassis 1 with screws 9, 9.

The gear 4 meshes with a drive gear (not shown) protruding into the notch of the end surface cam 7, and is rotated by the drive gear.

A shaft 13 is press-fitted in the center of the rotating body 10. The shaft 13 has a center hole of the shaft 2, a compression coil spring 16 and a washer 17 inserted therethrough, and a retaining ring 18 is locked.

In this way, the rotating body 10 is supported by the shaft 2 so as to be vertically movable and rotatable, and is biased downward by the compression coil spring 16.

The cutouts 14, 14 provided in the lower portion of the rotating body 10 are engaged with the pins 5, 5.

A shaft 11 is provided on the upper surface of the tip of the arm 10a provided on the rotating body 10.
Is erected, and an elastic pressure contact 12 is fitted on the shaft 11 and is locked by a retainer 11a.

A cam follower 15 is provided on the lower surface of the base end portion of the arm 10a, and the cam follower 15 is pressed against the cam surfaces 8a, 8b by the elasticity of the compression coil spring 16.

Next, the operation of the disc pushing mechanism 19 will be described with reference to FIGS. 4 and 5.

FIGS. 4A and 4B show a state in which the disc 24 is fed to the lowermost stage of the magazine 21.

Disk 24 is driven by the drive roller of the disk engineer.
It is sent in the direction and stops at the position shown in the figure.

At this time, the cam follower 15 provided on the rotating body 10 is in contact with the cam surface 8a, and the press contact 12 is stopped at the position B below the moving path of the disk 24. Next, the rotating body 10 is rotated by the gear 4, and the pressure contactor 15 rotates in the C direction shown in FIG.

When the pressure contactor rotates to the D position, the cam follower 15 provided on the rotating body 10 comes into contact with the cam surface 8b at a position higher than the cam surface 8a, and the pressure contactor 12 rises to the height of the disk 24.

Further, the pressure contactor 12 pushes the disk 24 into the magazine 21 while the pressure contactor rotates to the E position.

After that, the rotating body 10 is further rotated, and the pressure contact 12 returns to the B position.

Since the pressure contactor 12 is made of an elastic material such as rubber, it does not scratch the disc when the disc 24 is pushed in,
Further, since it is rotatably supported, the frictional resistance is small.

Further, an error in the mounting position of the pressure contactor 12 is also allowed by elastic deformation.

Therefore, the smooth pressing operation of the disc by the pressure contactor 12 is achieved, and the high speed processing is possible.

Moreover, the operation is completed by one rotation of the rotating body, and the mechanism is simplified.

Although the embodiment of the present invention is configured as described above, the invention is not limited to this. For example, instead of directly storing the disc in the magazine, the disc is stored in a state of being placed on a tray,
Alternatively, it may be transferred to the reproducing unit.

Further, although the embodiment shows the one in which the magazine is fixed, the present invention can be applied to the one in which the magazine moves or the one in which the magazine and the disc changer move.

As described above, according to the disc pushing mechanism of the disc changer of the present invention, since the moving distance of the pressure contactor for pushing the disc is short, the time required for the disc pushing operation is short and the mechanism is small.

Further, since the processing is performed by the rotational movement, the operation becomes smooth and the mechanism becomes simple.
